采用表面机械研磨处理（SMAT）方法，在Ti-6Al-4V合金表面形成纳米晶表面层。采用动电位极化曲线和电化学阻抗谱研究了Ti-6Al-4V在Ringer溶液中的腐蚀行为。所有研究的总体结果都表明SMAT对Ti-6Al-4V合金的腐蚀行为具有有益的影响，Ti-6Al-4V表面形成的氧化膜及其在生物环境中的稳定性对植入物的生物相容性起着决定性作用。在这项研究中，钝化膜Ti-6Al-4V表面上形成和它们的自然生长的林格氏溶液中进行了研究，通过显微硬度和X射线光电子能谱（XPS）。(C)2013爱思唯尔有限公司版权所有。
By means of surface mechanical attrition treatment (SMAT), a nanoaystalline surface layer was formed on a Ti-6Al-4V alloy. The corrosion behavior of Ti-6Al-4V in a Ringer's solution was investigated by potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) measurements. Overall results of all studies identified beneficial impacts of SMAT on corrosion behavior of Ti-6Al-4V alloy.The surface oxide film formed on Ti-6Al-4V and its stability in biological environments play a decisive role for the biocompatibility of implants. In this study, passive oxide films formed on Ti-6Al-4V surfaces and their natural growth in a Ringer's solution have been investigated by microhardness and X-ray photoelectron spectroscopy (XPS).
